To a/ZZ whom it may concern.-

Be it known thatI, NICHOLAS HOWARD EASTON, of Central Falls, in thecounty of Providence and State of Rhode Island, have invented a new anduseful Improvement in Bobbio-Holders for Spooling-Mac'nines, of

which the following is a specification.

This invention relates to a holder or support for a bobbin, while theyarn is being removed therefrom, and rewound upon a spool in a spoolingmachine; and it consists in the employment of a counter-balanced pivotedcradle or holder for the bobbin, and a pivotally held gravitatingtension arm, the said cradle and gravitating tension arm being arrangedto rock from side to side, to relieve the yarn from undue strain whileit is being wound from the bobbin onto the spool; the gravitating armserving to steady the bobbin at its drawing side, and produce therequired uniform tension upon the yarn.

In the accompanying drawings:-Figure l, represents a side viewlof abobbin-holder or support, embodying the invention, with the bobbin inplace therein. Fig. 2, represents a direct front end view, taken in linewith the axis of the bobbin. Fig. 3, represents a section taken in theline 3, 3, of Fig. l.

The bobbin holders or supports are intended to be located side by side,and to be mounted upon the spooling machine in any suitable manner, asby being attached to a rod or bar A, which runs longitudinally of themachine, each holder being placed in front of a spool, upon which theyarn of the bobbin is to be wound bythe usual mechanism.

is the inclined cradle, in the trough a, of which, the bobbin C isloosely placed, to rest .With its inner end against the head d; the

said cradle being loosely pivoted to the frame 4o D, by means of thepivot pin e and the center pointed screw e,shown by dotted linesin Fig.1, and provided with the counter-balancing weighty. i

The frame D is secured to the rod or bar A, by means of the set screw g,and is provided with the slots h, h', in which are pivotally held theopposite ends t', ft', of the swinging gravitating arm E, so that whilethe said arm has a swinging movement, with the swinging movement of thecradle B, and the bobbin C, it may also have an up and down movement;such up and down movement being caused by the tension of the yarn l), asit is being drawn from the bobbin against the side of the bar c, of thegravitating arm E, the pivot ends z', 4l, of the gravitating arm, rising.and falling as occasion requires in the slots hand h', in the frame.

The tension of the yarn b forces the bar c of the gravitating arm Eagainst the side of the yarn F on the bobbin, and tends to secure auniform tension between the bobbin and s the winding spool, an excess oftension being relieved by the resulting upward movement of thegravitating arm E.

I claim as my invention- The combination with the frame, and the l
